Upon entering the study all patients underwent physical exam with attention to: straight leg raising test (positive or negative), contralateral straight leg raising (positive or negative), knee and ankle stretch reflexes (0-3+), foot sensation (normal or decreased), strength (0-5) of quadriceps, foot dorsiflexors, foot plantar flexors, and ability to perform five heel lifts (0-5). Patients also completed three written instruments: a “12 Item Health Status Questionnaire” (13), a “Roland-Morris Disability Questionnaire” (14), and a “Roland-Morris Pain Rating Scale” (14). Also noted at the intake visit and each subsequent visit were the number of hours each patient was working or, if they were not employed or were retired, their estimated percent of daily living activities they were able to accomplish. Lastly, note was made of whether the patient had undergone epidural steroid injection or surgical intervention since the previous visit. Each patient underwent the same exam and completed the same questionnaires weekly for four weeks post recruitment, and then monthly for five months. This led to a total of 6 months of follow-up.
